If this is not the current name

then I guess it should be depreciated and this observation changed to Flammulaster erinaceellus. According to index fungorum the current name is Flammulaster erinaceellus (Peck) Watling [as ‘erinaceella’] 1967

Christine, you may want to search MO via “Flammulaster.”

That’s what seems to be the current genus for this mushroom.

These are fruiting now, I don’t think they are that uncommon, but maybe commonly misidentified as Pholiota.

Cool find.
